Answer:
1. Radius = 84.65 in
2. Circumference = 531.65 in
3. Diameter = 169.3 in
Step-by-step explanation:
1] In order to find the area of a circle, we use the formula
Area of a circle = πr²
Where r is the radius. So substitute the value of the area of the circle in the formula, to find the radius r.
22511 = π r²
r² = 22511 ÷ π
r =
<u>r = 84.65 in</u>
2] Now that we found the radius, we can easily find the circumference using the formula:
Circumference of a circle = 2πr
Substitute the value of r in the formula.
Circumference = 2 × π × 84.65
<u>Circumference = 531.87 in</u>
3] The diameter is twice the radius, so:
diameter = r × 2
diameter = 84.65 × 2
<u>diameter = 169.3 in</u>
